Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the pattern repeats uniformly throughout the circumference of the tread;

FIG. 2 is a front elevational view thereof;

FIG. 3 is a right side elevational view thereof; the opposite side being a mirror image thereof; and,

FIG. 4 is a fragmentary front view, showing the tread pattern in greater details;

FIG. 5 is a cross-sectional view taken along line 5—5 and in the direction of arrows in FIG. 4.

In the drawings, the unlined circumferential and diagonal portions of the tread represent grooves having the depth shown in FIG. 5.

The broken line showing of a tire sidewall and inner bead, including the peripheral boundary between the claimed tread portion and the sidewall, represents unclaimed environmental subject matter. 

The ornamental design for a tire tread, as shown and described.
